Abstract

L'INVENTION CONCERNE UN APPAREIL DE COMMANDE DE MOTEUR SYNCHRONE. ELLE SE RAPPORTE A UN MOTEUR D'ENTRAINEMENT D'UNE TOUPIE 50 D'UN GYROSCOPE DE PRECISION. CETTE TOUPIE 50 EST COMMANDEE PAR UN CIRCUIT ASSERVI A UNE VITESSE INFERIEURE A LA VITESSE DE SYNCHRONISME DU MOTEUR; UNE FREQUENCE DE REFERENCE, CREEE PAR UN GENERATEUR DE FREQUENCE DE ROTATION DE TOUPIE, EST SYNCHRONISEE SUR UNE REFERENCE DE FREQUENCE DE GRANDE STABILITE SI BIEN QUE LA VITESSE DE LA TOUPIE EST MAINTENUE AVEC PRECISION. LES POLES DE L'ANNEAU D'AIMANTATION DU MOTEUR TOURNENT CONSTAMMENT AUTOUR DE L'ANNEAU ET LEUR EFFET SUR LA POLARISATION MAGNETIQUE MOYENNE A UNE VALEUR MOYENNE NULLE. APPLICATION AUX GYROMETRES A SUSPENSION SOUPLE.THE INVENTION RELATES TO A SYNCHRONOUS MOTOR CONTROL APPARATUS. IT RELATES TO A DRIVE MOTOR OF A SPINDLE 50 OF A PRECISION GYROSCOPE. THIS SPINDLE MOULDER 50 IS CONTROLLED BY A CIRCUIT SLACED TO A SPEED LOWER THAN THE SYNCHRONISM SPEED OF THE MOTOR; A REFERENCE FREQUENCY, CREATED BY A SPINDLE ROTATION FREQUENCY GENERATOR, IS SYNCHRONIZED ON A FREQUENCY REFERENCE OF HIGH STABILITY SO THAT THE SPEED OF THE SPINDLE MOULDER IS MAINTAINED WITH PRECISION. THE POLES OF THE MOTOR MAGNET RING CONSTANTLY ROTATE AROUND THE RING AND THEIR EFFECT ON THE AVERAGE MAGNETIC POLARIZATION HAS A ZERO AVERAGE VALUE. APPLICATION TO SOFT SUSPENSION GYROMETERS.
